COLLAR-BUTTON.

Specification of Letters Patent.

Patented Aug. 11, 1914.

Application filed February 24, 1914. Serial No. 820,738.

To all whom it may concern:

Be it known that I, EDWARD L. ANDERSON, a citizen of the United States, residing at Attleboro, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Collar-Buttons, of which the following is a specification.

This invention relates to certain new and useful improvements in collar buttons, and the primary object thereof is to provide improved means for efiecting connection of the post with the pearl back.

A further object of the invention is to provide means for uniting the post and back which will effectively retain the parts in rigid connected relation, and which will prevent contact of the more or less raw edges of the post base with the body or clothes of the wearer.

In the drawingsFig.ure1 is a side elevation partly broken away and in section showing the parts related prior to completion. Fig. 2 is a similar view of the completed collar button, and Fig. 3 is a view similar to Fig. 2 of a modified form of the invention.

In proceeding in accordance with the present invention the pearl back 1 has a central aperture 2 and a countersunk portion or depression 3 which is concentric to the aperture 2. The post 1 which is of tubular form has its base portion doubled upon itself at 5 to provide a bearing or abutment which seats on the inner face of the back 1. The end 6 of the post base which is extended out from the bearing or abutment 5 projects through the aperture 2 as shown in Fig. 1 after which its free end portion is spun or swaged into the countersunk part or depression 3, as illustrated in Fig. 2, in which position it will be seen that the raw edge of the end 6 is disposed inwardly of the outer face of the back 1, and is thereby protected by the same, preventing contact of the raw edge with the clothing of the wearer. The protection of the raw edge of the end or extension 6 is complete and effective and overcomes an objection which has heretofore proven diflicult of solution. Preferably, when swaged or spun into the posit-ion illustrated in Fig. 2 of the drawings, the raw edge of theend or extension 6 contacts with the wall which defines the countersunk part or depression 3, thus contributing to the effective and rigid In the modified form. of the invention depicted in Fig. 3 of the drawings, the sole distinction presented is that of the tapered bottom wall 3 of the depression or countersunk part 3, and the corresponding change in the conformation of the end of the post which is swaged or spun so as to conformably engage the tapered bottom wall 3, the extension or end of the post thus having a tapered or flared portion 7.

' In bot-h forms of the invention, the swaged or spun end of the post cooperates with the thickened or enlarged doubled portion 5 to firmly clamp the pearl back in position, and since the doubling over of the post to form the bearing 5 provides a rounded edge for same, and due to the fact that the raw edge of the extension is disposed between the innor and outer faces of the pearl back, it will be apparent that no rough edges or otherparts of the base metal are exposed which would prove objectionable for manifest reasons.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a collar button, a tubular post having a doubled over part disposed in spaced relation to the end of its base portion to provide an abutment, the post being extended beyond the doubled over part, and a pearl back having a central aperture through which said post extension is projected, and

also having a countersunk portion into which the end of the extension is outwardly swaged so as to cause the'swaged portion to be disposed between the inner and outer faces of the back and to have its periphery covered by the bounding wall which said countersunk portion provides.

2. In a collar button, a tubular post having an abutment and an extension which projects beyond the abutment, and a back which has a central aperture through which said extension projects and also having a countersunk part into which the free end portion of the extension is outwardly swaged name to this specification in the presence of so that the outer face of the back extends two subscribing Witnesses. beyond said swaged portion and therlatter has its periphery covered by the bounding EDVARD ANDERSON 5 Wall which said'countersunk portion pro- VVit-nesses:
